poor performing SIMO bucks?

Development Boards Artemis

Inductors are expensive and large compared to other passive components. we have benchmarked the Artemis in LDO mode and using the SIMO buck…we get an an improved SIMO buck current draw of only 40 micro amps compared to the LDO. Maybe we have either configured the SIMO buck incorrect? Has anyone else done a SIMO LDO current draw comparison?

If our results are correct surely there is no real justification of including the buck inductors in the Artemis module?

Thanks for reaching out to us on this.

We are not sure about about whether this is a pervasive issue; if we do confirm such we will reply with our data.

Hope this helps, and happy sparking!
